The Crown of Thorns, or Euphorbia milii, is a succulent plant native to Madagascar. Renowned for its distinctive beauty and exceptional resilience, this plant belongs to the Euphorbiaceae family. It is characterised by its thick, spiny stems, often intertwined, which can grow up to 1.5 metres in height. Additionally, its bright green foliage, sometimes tinged with red depending on light conditions, creates a striking contrast with its delicate flowers. These blossoms, technically bracts, come in a range of colours, from red and pink to white and yellow.
In a setting such as the botanical garden at Au Bois Vert, the Crown of Thorns adds an exotic and vibrant touch while requiring minimal maintenance. Indeed, it thrives in harsh conditions, tolerating intense heat, prolonged drought, and poor soils. As a result, it is an ideal choice for succulent enthusiasts and travellers exploring lodges and hotels in Antananarivo and Ivato, seeking fascinating plant species to admire.
Moreover, the Crown of Thorns offers an almost continuous bloom throughout the year, making it particularly valued in botanical gardens and landscaped spaces within hotels and restaurants. In addition, it attracts pollinators such as butterflies, bringing a lively and dynamic element to any environment where it grows.
Plant use
The Crown of Thorns is more than just an ornamental plant; it also has several practical and symbolic uses. In its native Madagascar, this plant holds an important place in local traditions. The inhabitants make use of its latex—despite being toxic—for medicinal purposes, such as treating certain skin conditions. However, careful handling is essential, as the latex can cause irritation. Beyond its practical applications, this hardy succulent carries deep symbolic significance. It is closely linked to the Passion of Christ, which explains its nickname, and is often used as a decorative plant during religious celebrations. Its distinctive appearance and resilience serve as a reminder of qualities such as strength and perseverance. In places like the botanical garden at Au Bois Vert, the plant enhances the visitor experience, particularly for those staying in the lodges or dining at the on-site restaurant. Thanks to its low water requirements, it is also an excellent choice for sustainable gardening projects in arid or semi-arid regions. Its appeal extends far beyond Madagascar; it is cherished worldwide for its adaptability and ability to thrive both in pots and in open gardens. Tourists visiting Ivato or Antananarivo can admire its beauty while learning about its fascinating history in the enchanting setting of the botanical garden.
